With 0.41% of the land around it burning each year, Duck Lake 7 sits in the high wildfire band (16% within 25 km since 1986). Earthquake risk in Duck Lake 7 is ordinary: NRCan’s model puts building losses at $0.016 a year per $1,000 of value, close to the typical town’s $0.030. In Health Canada’s survey, 17% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Duck Lake 7 grades D− for hazard risk, with wildfire counted against it.

Hazard risk in Duck Lake 7: D−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Duck Lake 7 with little fire nearby would get no credit for it.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
5.2% of the land near Duck Lake 7’s homes has burned since 1986, 16% within 25 km
Fires mapped since 1986 around where Duck Lake 7’s residents live, and the fuel next to their homes.
The yearly burn rate around Duck Lake 7 is 0.41%, against 0.000% for the typical Canadian town: the high band.
Within 5 km of Duck Lake 7, 17% of the land is forest fuel; widen the ring to 25 km and it is 51%.

The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped.

Get ready for what Duck Lake 7 faces
What to do about the hazards Duck Lake 7 faces, and what to ask before you buy.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Has it had a radon test?
- Check the address on the flood map.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Duck Lake 7 takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Duck Lake 7.
- Wildfire counts one way. For Duck Lake 7, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Duck Lake 7’s census subdivision (a neighbourhood shows its city’s).
